Consumer advocates are making a last-ditch effort to hinder the $1 billion
merger of Internet advertiser DoubleClick with market researcher Abacus
Direct, charging that the deal will be an assault on personal
privacy.

Although privacy groups have sent letters asking the companies'
shareholders to reject the merger and have complained to the Federal Trade Commission about the privacy
implications, approval of the deal is scheduled to be voted on tomorrow.

Opponents of the merger worry that it will increase the likelihood of
corporate abuse of customer data by bringing together Net surfing habits
obtained from the 5 billion ads DoubleClick serves per week and the 2
billion personally identifiable consumer catalog transactions recorded by
Abacus.

Still trying to turn up the heat on the merger, privacy groups planned to
meet with FTC commissioners Sheila Anthony and Mozelle Thompson today to
call for the agency to use its existing jurisdiction over unfair business
practices to crack down on online profiling and to scrutinize the pending
deal. Earlier this month the
FTC examined profiling, a
growing trend in which firms piece together Net users' personal information
and surfing habits to target them with advertising and new services.

Advocates also sent a new round of letters to
managers of so-called socially responsible mutual funds, such as the
Citizens Emerging Growth Fund, Dreyfus Third Century Fund and Smith Barney
Concert Social Awareness Fund, asking them to drop DoubleClick and Abacus
from their portfolios.

"The companies aim to automatically and invisibly link your offline
identity with your movements on the Net--that is a terrible change to the
medium," said Jason Catlett, founder of Junkbusters, a clearinghouse for
privacy-protection measures.

"It's a full frontal attack, funded by Wall Street, on anonymity on the
Net," Catlett added. "We are calling for the FTC to put an immediate halt
to online profiling pending the development of a suitable regulatory
framework."

A representative for Abacus referred CNET News.com's request for a statement
on the privacy groups' protest to DoubleClick, for which representatives
weren't immediately available to comment.

DoubleClick, which is a member of the Online Privacy Alliance and pledges
to disclose its data-collection practices, has contended in the past that
it doesn't gather personally identifiable information from Net users.

"In the course of delivering an ad to you, DoubleClick does not collect any
personally identifiable information about you, such as your name, address,
phone number or email address," the company's privacy policy states.

But DoubleClick does collect personal information through other means, such
as surveys, purchase forms and its own sites.

"For the Web sites owned or controlled by DoubleClick, [we] may ask
for and collect such personal information," DoubleClick's data-collection
policy states.

For example, DoubleClick's site NetDeals.com collects visitors' names,
their home and email addresses, and birth dates through contest entries.

"We combine that information with other information about you that is
available to us," the privacy policy on NetDeals states. "This includes
other personally identifiable information and certain non-personally
identifiable information, such as the type of browser you use."

Citing the NetDeals.com disclosure, privacy advocates warn that DoubleClick
can match unique identification numbers that it assigns to surfers'
computers via cookies
with personal information collected through NetDeals and other sites
such as IAF.net. People can "opt out" of DoubleClick's cookie system
through its Web site.

The NetDeals site also states, "We participate in the DoubleClick
Information Alliance and share the information we have about you with that
Alliance." DoubleClick's privacy statement, however, doesn't mention the
alliance, and a search for "DoubleClick Information Alliance" on its site
doesn't turn up an explanation either.

In their letter to mutual fund managers, the privacy groups argue that the
capability to combine Net users' cookies with any personal information, and
to match those records with offline sales databases, is a huge threat to
consumer privacy.

"The trend threatens to fundamentally change the nature of the Web, from
one where people's movements in cyberspace are generally anonymous to one
where their identity and a large profile moves around with them," states
the letter signed by Catlett, the Electronic Privacy Information Center and
Privacy International.

"Divest any holdings of DoubleClick and Abacus Direct as soon as possible,"
the letter continues. "Add DoubleClick and Abacus to 'screening' lists of
companies that are to be excluded from investment based on social criteria,
specifically a disregard for human rights."

DoubleClick's own privacy statement indicates that its practices may change
in the future when it comes to building profiles on Net users.

"DoubleClick has no rights or plans to use Abacus' database information
prior to the completion of the merger," the policy states. "Upon completion
of the merger, should DoubleClick ever match the non-personally
identifiable information collected by DoubleClick with Abacus' database
information, DoubleClick will revise this Privacy Statement to accurately
reflect its modified data-collection and data-use policies and ensure that
you have adequate notice of any changes and a choice to participate."

The advocates' quest for funds to relinquish any holdings in Abacus and
DoubleClick won't be easy. Both firms are faring well in the market, with
DoubleClick's shares closing up 8.31 at 158 today, while Abacus closed up
10.5 at 167.31.
